The failure on both of my unit have been the crystals not oscillating. A tweak on the capacitors got one to work, the other one seemed to have a flaky sock; /archives//html/TenTec/2015-10/msg00167.html (8,920 bytes)

I should have know this from my Omni-A/D/C experience. Now on to #2: On transmit I see no power, and no current draw. Whats the best way to; /archives//html/TenTec/2015-10/msg00202.html (8,668 bytes)

At the risk of overthinking this: - no ALC light at all - zero output (both finals gone?) - zero additional current (finals are not shorted?) - both open? maybe th; /archives//html/TenTec/2015-10/msg00205.html (10,987 bytes)
